Stress-adapted Immunity: The Integrated Stress Response as a Driver of S. aureus Biofilm Persistence 2256775

Craniotomy, a neurosurgical procedure for treating brain tumors, epilepsy, and cranial bleeds, carries a 1-5% infection risk, often due to Staphylococcus aureus biofilm formation, rendering infections tolerant to antibiotics and immune clearance. Treatment often requires multiple surgeries, heightening patient mo...

Neutrophil Reprogramming Fuels Immunosuppression in Staphylococcus aureus Biofilm Infection 2256977

This findings reveal that S. aureus biofilms exploit TLR2-MyD88 signaling to reprogram neutrophils into immunosuppressive G-MDSC-like cells, which highlights both bacterial-derived TLR2 ligands and host TLR2 signaling as promising therapeutic targets to restore antimicrobial immunity in neurosurgical infections.
